  您可以编写自己的POJO以匹配来自API网关的请求，然后您就可以从getter访问资源路径 .

  POJO示例：

  public class LambdaFunctionHandler implements RequestHandler<Object, Object> {
  
      @Override
      public Object handleRequest(AwsProxyRequest input, Context context) {
          String resourcePath = input.getRequestContext().getResourcePath();
  
          return resourcePath;
      }
  
  }
  
  public class AwsProxyRequest {
  
      //-------------------------------------------------------------
      // Variables - Private
      //-------------------------------------------------------------
      private ApiGatewayRequestContext requestContext;
      ....
  
      //-------------------------------------------------------------
      // Methods - Getter/Setter
      //-------------------------------------------------------------
  
      public ApiGatewayRequestContext getRequestContext() {
          return requestContext;
      }
  
  
      public void setRequestContext(ApiGatewayRequestContext requestContext) {
          this.requestContext = requestContext;
      }
  
      ....
  
  }
  
  public class ApiGatewayRequestContext {
  
      //-------------------------------------------------------------
      // Variables - Private
      //-------------------------------------------------------------
  
      private String resourcePath;
      ...
  
      //-------------------------------------------------------------
      // Methods - Getter/Setter
      //-------------------------------------------------------------
  
      public String getResourcePath() {
          return resourcePath;
      }
  
  
      public void setResourcePath(String resourcePath) {
          this.resourcePath = resourcePath;
      }
  
      ....
  }
  

  如果您想要完整的代理请求POJO，可以从here找到它们 .

  感谢Ka Hou leong的指导，我解决了以下问题：

  1）在Maven中为aws-serverless-java-container添加了依赖项

  <dependency>
      <groupId>com.amazonaws.serverless</groupId>
      <artifactId>aws-serverless-java-container-core</artifactId>
      <version>0.4</version>
  </dependency>
  

  2）修改了我的LambdaFunctionHandler类以使用AwsProxyRequest和AwsProxyResponse：

  import com.amazonaws.serverless.proxy.internal.model.AwsProxyRequest;
  import com.amazonaws.serverless.proxy.internal.model.AwsProxyResponse;
  import com.amazonaws.services.lambda.runtime.Context;
  import com.amazonaws.services.lambda.runtime.RequestHandler;
  
  public class LambdaFunctionHandler implements RequestHandler<AwsProxyRequest, Object> {
  
      public Object handleRequest(AwsProxyRequest input, Context context) {
          AwsProxyResponse response = new AwsProxyResponse();
          String resourcePath = input.getRequestContext().getResourcePath();
  
          response.setStatusCode(200);
          response.setBody(resourcePath);
      return response;
      }
  }
  

  3）修改了我的API网关方法集成请求设置以使用Lambda代理集成 .

  从这里我可以访问输入对象中的所有内容作为AwsProxyRequest，并将作为AwsProxyResponse操作响应与我想要响应的任何内容 .
